Error analysis is a systematic approach used to identify and evaluate mistakes in various fields, such as language learning, mathematics, and computer programming. By examining errors, educators and researchers can understand the underlying causes and patterns, which helps improve teaching methods and learning outcomes. In language education, for example, error analysis focuses on the types of mistakes learners make, such as grammatical errors or pronunciation issues. This information can guide instructors in tailoring their lessons to address specific challenges, ultimately enhancing the learning experience and promoting better language proficiency.
